ES, the chances of your dying from a childhood injury are slim now. You may have life-long issues as a result of it though. I had a head injury when I was about 3 and have realized it has affected me all my life. Also like you, I've had other injuries along the way, so who knows what caused what? If you haven't told your doc about all of these, do so. Then you can be evaluated as to what you can fix and what you can't.
